Answer: An exact number has infinite significant numbers
Explanation:
For instance, 00340 has two significant figures, while 009.00 x 10¯4 has three significant figures.
But exact numbers are gotten by counting the amount of something that is present. Hence, they are not measurements gotten by using calibrations of instruments.
Therefore, Exact numbers, like the number of animals in a cage, have significant figures that are INFINITE in value.
